Still pretty new to GIS, but Ive been working on assembling a map with ~20 vector layers over the past couple of weeks. Its finally to a point where Im ready to export. Ive been experimenting with various export methods for a few days now, and I cant seem to get what Im looking for.
Map info - its massive, covers over a million acres. my goal is to have it printed on a banner, 10 feet wide, by however tall makes sense to preserve the aspect ratio For prints of this size, DPI needs to be high, ~300 or more, from what Ive read Scale - Im trying to keep it around 1:24000, or even 1:20000
I have been trying for either a PDF or a TIF file.
When I use the exact settings I want, the export fails with one of those errors about it being too big, cant allocate enough memory, ect.
This happens for both the Project -> export, and the print composer methods.
When I tweak the settings, compromising on either scale, or dpi, I eventually get a successful output, kind of. The files it creates look clean, open up fine, but they have part of map cut off, always the far right edge. And sometimes there is even a strange black block that appears in the area that was cutoff. It seems as though the exporting process works left to right across my map, and fails at some point, but doesnt report it as a failure.
Any suggestions for what else I might try?
